Application filed April 18, 1913. Serial No. ?'62,Q98.

To all nut-)1?! it may concern Be it known that I, Ina H. SPENCER, a citizen of the United States, and a resident of West Hartford, in the county of Hartiord and ntate of Connecticut, have invented a new and improved Valve for Organ-Blowers, of which the :tollov-cingis a specification.

My invention relates more especially to the class of apparatus used for supplying air to musical instrinnents, more especially pipe organs, and an object of my invention,

among others. is to provide an apparatus of" this class by the use of which the flow of air shall be accurately controlled in proportion to the amount used in playing the organ; and a further object of the invention is to provide such an apparatus by the use of which the increase or decrease of the amount of air shall be even and steady.

One lorin of apparatus embodying my invention and in the construction and use of which the objects hcreinal'sove set out, as well as others, may be attained, is illus tratcd in the accompznying drawings, in which- Ilig'ure 1 is a diagrammatic view illustrating the construction and operation of my improved device. Fi 2 a detail view .in central lmigitudinal section through an air conduit embodying my invention. 3 is a top plan view of the same, the scale being enlarged in the last two views.

.l n an apparatus vtor supplying air to pipe organs. and especially those. as frequently made. that have a number of reservoirs for supplyinguiizto difi'crent sets of pipes, it essential that such supply shall be kept at a constant predetermined pressure in each of the reservoirs. in order that the valves controlling the supply to the dili'ercnt reservoirs shall work smoothly and without liability of jumping action. The pipe that conveys the air from the pump or blower readily conveys sounds made by such pump or blower, audit is therefore important that while the degree of pressure shall be maintained constant for supply to the diii'ercnt reservoirs. the passage through the pipe or conduit shall be closed when little or no air is being used by the organ, this to prevent the objectionable noise of the pump from being conveyed at such time to the ears of the persons within sound of the organ, this noise being downed when theorgan is played loudly, causing much air to pass. 'l'ne requirements of the ditierent sets of pipes supplied from the reservoirs are such as not to require the same pressure of an: in all of the reservoirs, and m improved. apparatus, illustrated and described herein, provides means whereby the pressure to the seve 'al reservoirs, irrespective of their location, one with respect to another. may be so easily regulated that smooth even aetion of the valves controlling entrance to the reservoirs will be obtained, and the sup-- ply of air for delivery to the r scrvoirsflwll bein direct proportion to the amount of be ng; used, my improved controlling means being extremely sensitive in actionhnd retpiirinfo little power for its operation.

In the acconu ianying drawinqjs thr.- le t r denotes a blower or pump any ap 'iroved 7 61111 and construction. preferabl a multible stage fun from which a conduit i er;- tends and is euuiloyed to supply air to the dili'crent reservoirs 7). the del very to the res- Ll'YHllr; being through branch pipes 13. from the main conduit These reservoirs are each oi the usual and well known. construc tion. each including a collapsible section (Z havin snrings or like members 6 located be tween. ruts g and the top f of the reservoirs for forcing the top tov-xard the bottom to move the valve 72 from its seat and allow air to enter the reservoir through the opening 2''. a rod 7.: connecting the valve with the top of the reservoir.

All of the parts just described are of old and well lniown construction. in, the operation of thes devices. an objection has been encountered from the fact that the valves it when they reach a position nearly closing the opening 5 are forced suddenly into engagement with their seats, causing an objectionable noise and a vibration in the" sound. produced by the organ, and under certain conditions. opening; and closing movement of the valves-will be repeated in rapid succession. By my improved apparatus I have provided means whereby the siiip 'ily of air for delivery to these reservoirs, the pressure in which varies one from another, (H7: ing to the requirements of use, mayrhe so regulated that not only is this objectionable damper being formed. to

A iever 27 the. valve 7 and a "Weight 29 on said lever determines the amountof pressure that Wiii 3 required to moi "c the pisjion 15, and by means of this lever the amount of pressure which will exist for supplying air to the organ may be nicely feguiated.
